2.6.33-stable review patch. If anyone has any objections, please let us know.

------------------

From: Daniel Ritz <daniel.ritz(a)gmx.ch>

commit 68f194e027ecfbbc8d5515bc40787e542eed59e9 upstream.

For some unknown reason, on a MacBookPro5,3 the iSight sometimes report
a different video format GUID. This patch add the other (wrong) GUID to
the format table, making the iSight work always w/o other problems.

What it should report: 32595559-0000-0010-8000-00aa00389b71
What it often reports: 32595559-0000-0010-8000-000000389b71
